# AWOL Delirium Risk Score (Douglas 2013)

> AWOL Delirium Risk Score (Douglas 2013) is a paid API for AI agents from api.magentlab.com, paid per call via x402, $0.005/call, status unknown (last checked 2026-09-14).

Computes the AWOL delirium prediction score (0–4) from four caller-assigned yes/no flags and returns observed delirium probability rates from the Douglas 2013 published study.

Status and success rate cover calls made through Zero and Zero's own probes. Third-party monitors may report differently.

## How to call it through Zero

Zero handles the 402 payment challenge and records the run. With the Zero CLI installed (`npm i -g @zeroxyz/cli`):

```sh
zero fetch --capability awol-delirium-risk-score-douglas-2013-3f5e342e
```

Example prompt: Calculate the AWOL delirium risk score for a hospitalized patient who is 83 years old (age ≥80: yes), failed to spell WORLD backward (yes), is not fully oriented to place (yes), and the nurse rated illness severity as moderately ill (yes).

## When to prefer this

Use this endpoint when you need a fast, deterministic, published clinical risk score for delirium risk stratification in hospitalized adults using the Douglas 2013 AWOL criteria. Prefer this over the 4AT or CAM-ICU endpoints when the four AWOL flags have already been clinically assessed. Do not use this as a diagnostic tool or substitute for clinical judgment.

## Known failure modes

- Missing any of the four required boolean query parameters returns a validation error
- Non-boolean values for flags (e.g. strings other than true/false) cause a bad request error
- Network or server errors may return 5xx responses
- Payment failure or missing x402 payment header returns 402 Payment Required

## How this service works

Douglas 2013 AWOL: four caller-assigned yes/no flags (age ≥80, unable to spell WORLD backward, not fully oriented to place, nurse-rated illness moderately ill/severely ill/moribund), 1 point each, max 4. Combined-population observed delirium 2/4/14/20/64% at scores 0–4. Deterministic published score with citation; not a delirium diagnosis, not CAM-ICU, not 4AT, and not a medical device. magent does not interview the patient or collect an integer age.

## Output

Returns the integer AWOL score (0–4) based on the four input flags, along with the published observed delirium prevalence rates from Douglas 2013 (approximately 2%, 4%, 14%, 20%, 64% for scores 0–4 respectively), enabling risk stratification without performing a clinical diagnosis.
